Armlock

An armlock is when someone grabs your arm and stops it from moving, like when you're trying to reach for something but someone else stops your arm. It's kind of like a really strong hug, but just on your arm. It might hurt a little bit because your arm is stuck and can't move, but it's usually done in a safe way so you don't get hurt. Some people practice armlocks in a sport called martial arts where they learn how to do it to protect themselves if someone tries to hurt them. It's important to remember that armlocks should only be done safely and with the help of someone who knows what they're doing.
